The Element of Paaw in Marsupials and the Ear Region of Philander opossum (Linnaeus, 1758) (Didelphimorphia, Didelphidae)
ABSTRACT A small piece of cartilage or bone, the element of Paaw, occurs in the tendon of the stapedius muscle in some extant marsupial and placental mammals. It has been nearly a century since theExpand
Therian Femora from the Late Cretaceous of Uzbekistan
Femora referable to metatherians and eutherians recovered from the Bissekty Formation, Dzharakuduk, Kyzylkum Desert, Uzbekistan (90 Mya), are described. Fourteen isolated specimens were sorted basedExpand
Allqokirus australis (Sparassodonta, Metatheria) from the early Palaeocene of Tiupampa (Bolivia) and the rise of the metatherian carnivorous radiation in South America
The dental morphology of Allqokirus australis is extremely similar to that of Patene simpsoni from the early Eocene of Itaboraí (Brazil) and presents distinct (although incipient) carnivorous adaptations. Expand

Caudal cranium of Thylacosmilus atrox (Mammalia, Metatheria, Sparassodonta), a South American predaceous sabertooth /
The caudal cranium of the South American sabertooth Thylacosmilus atrox is described in detail, with emphasis on the constitution of the walls of the middle ear, cranial vasculature, and major nerve pathways. Expand
Evolution des caractères crâniens et endocrâniens chez les Afrotheria (Mammalia) et phylogénie du groupe
L'etude des caracteres basicrâniens et endocraniens chez les vertebres fossiles et actuels connait un regain d'interet depuis quelques annees. Ces caracteres beneficient en effet d'une bonneExpand

An isolated ankle bone of a metatherian from the early Eocene Tingamarra Local Fauna in northeastern Australia is described and compared with a range of marsupials and stem-metatherians strongly suggest that the absence of the CLAJP in QM F30060 is plesiomorphic, and that this specimen represents the first unequivocal non-australidelPHian (‘ameridelphian’) meetatherian known from Australia.

The Most Ancient Xenarthran Petrosal: Morphology and Evolutionary Significance
An isolated petrosal from the middle Eocene of northwestern Argentina assigned to Dasypodinae is described and hypotheses of evolutionary change in the auditory region of cingulates, including the medial expansion of the roof of the post-promontorial tympanic sinus and the emergence of a conspicuous crista petrosa are proposed.

Morphological variation in the ear region of pleistocene elephantimorpha (Mammalia, Proboscidea) from central Texas
Within the inner ear, the absence of the secondary lamina suggests evolution of low‐frequency hearing in extinct proboscideans, which is known for extant elephants. Expand
